摘要： The invention provides a pump with a pulsation suppression device which can further enhance the effect of suppressing pulsation. According to the invention, in one side portion of a pump head wall 1 having inflow and outflow passages 2 and 3, a first bellows 7 which is driven so as to extend and contract by an air cylinder portion 14, and check valves 16a and 16b which alternately open and close a pump working chamber 9a formed in the first bellows 7 are disposed to constitute a reciprocal pump portion 4. In the other side portion of the pump head wall 1, a pulsation suppressing portion 5 is configured so as to have a second bellows 18 that is extendable and contractible, and that forms: a liquid chamber 20a which can temporarily store liquid that is to be discharged from the pump portion 4; and an air chamber 20b which is isolated from the liquid chamber 20a. The pulsation suppressing portion absorbs pulsation of the liquid which is discharged from the pump portion 4, by a change in the capacity of the liquid chamber 20a. The extension rate of the second bellows 18 is set to be larger than that of the first bellows 7.

摘要： The present invention relates to a pulsation suppression device which is interposingly used in a liquid transporting pipe through which a chemical liquid such as a surface washing liquid for washing an IC is transported by a reciprocal pump. The pulsation suppression device of the present invention has: a bellows which partitions the interior of the device body having a sealed container-like shape, into a liquid chamber and an gas chamber; an operating rod which is reciprocated in interlock relationship with the bellows; and an extension and contraction restricting mechanism which, when the bellows extends to a predetermined value, is contacted in parallel with a closed end face of the bellows, thereby restricting further extension of the bellows. Furthermore, the pulsation suppression device of the present invention has a guide for making the reciprocal operation of the operating rod coincident with the extension and contraction directions of the bellows. The guide is made of a low-friction resin material. According to the present invention, pulsation due to the discharge pressure of the transported liquid is absorbed and the amplitude of pulsation is suppressed to a low level. Moreover, the bellows used in the pulsation suppression device is prevented from being damaged, and the pulsation suppression function can be stabilized.

摘要： A bellows that is extendingly and contractingly deformable in the axial direction is placed in a pump body and forms a liquid chamber inside the bellows. A suction portion and a discharge portion are formed in an inner bottom face of the pump body facing the liquid chamber. Liquid is sucked from the suction port into the liquid chamber by extension of the bellows, and the liquid in the liquid chamber is discharged from the discharge portion by contraction of the bellows. The extending and contracting portion of the bellows which is configured by forming ridge-like folds and valley-like folds in a vertically alternate and continuous manner is formed into a shape in which the lower one of upper and lower lamella portions of each of the ridge-like folds, or the lower lamella portion is inclined downwardly toward the axis defining the axial direction, not only in an extending state but also in a contracting state. Even in the case where liquid containing a sedimenting material such as slurry is used, therefore, the sedimenting material can be prevented from sedimenting and stagnating in the extending and contracting portion of the bellows.

摘要： A bellows pump having a pump body including a suction path and a discharge path for a fluid and a bellows which is placed in a state where a basal end flange is airtightly fixed to the pump body to form a pump chamber with respect to the pump body. The bellows pump further comprises an actuation plate which is attached to a head portion of the bellows so as to cause the bellows to expand and contract with respect to the pump body. The bellows is further configured so that an airtight space is formed with between the actuation plate and a cup shape section formed in the head portion, such that a pressure rise can be absorbed and relaxed by contraction of the space portion caused by elastic film deformation of the thin head portion which faces the space portion.
